To all who'm, it may concem siding at Toledo, in the 4county ofLucas and ltion, reference being. had therein 7 `bling the' same. w

The invention` felate's to roller bearings loads, and has particular 'reference 'to' the peculiar construotionof parts which permts of easily .manufacturing and assem- It is also an object' of-th'e cnstmaiento maintain thesame ratio -of speed between all .bearing, and.
